HelloPharmacist Scorecard of Lemon Vervain Powder by TerraVita Premium Collection

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: lemon vervain powder. Lemon vervain (also called verbena) is an herb traditionally used for digestive and respiratory support, though the strength of evidence behind those uses varies.

The powder form allows you to mix it into water, tea, or other beverages.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Lemon product and its label doesn't state a use — see Lemon's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence behind lemon vervain for hay fever, anxiety, respiratory infections, high blood pressure, and kidney stones is currently insufficient—we don't have enough reliable data to rate whether it works for these purposes. If you're thinking about it for one of these reasons, talk with your doctor about whether there's a better-studied option available.

The evidence, ingredient by ingredient Lemon

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Lemon as a food or drink is generally well tolerated in the amounts you'd find in normal eating and drinking. In this powder form, you're getting a larger medicinal amount, and safety data on that level hasn't been thoroughly studied.

The main side effect to know about is gastrointestinal upset: in one trial, fresh lemon juice at higher doses caused heartburn in about one in five users and stomach pain in a smaller number, compared to much lower rates in a placebo group. If you have reflux or a sensitive stomach, start with a small amount and see how you feel.

Minor interactions only
Known Interaction Concern · database check
Minor only

Only Minor-severity interactions are documented for these ingredients.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Lemon.
  • The most serious interaction on file is rated Minor.
  • For scale: 1 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

If you take itraconazole (Sporanox), an antifungal medication, check with your doctor or pharmacist before using this product. It may increase itraconazole levels in your blood.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Only minor medication interactions are documented, and safety information is well characterized.

Lemon Vervain Powder is generally well tolerated, but it's not a proven remedy for any specific condition based on current evidence. The main practical concern is one drug interaction with itraconazole.

Before you start, check with your doctor or pharmacist about your medications—especially if you're on an antifungal—and about whether this powder is right for your stomach.

Itraconazole (Sporanox)

Theoretically, taking itraconazole capsules or tablets with a beverage containing lemon might increase the levels and clinical effects of itraconazole.
In one case report, dissolving itraconazole tablets in a small amount of specific beverages containing lemon prior to administration increased the level of itraconazole in a lung transplant patient. In this case, the increased bioavailability was desirable and was likely due to improved tablet dissolution in the acidic beverage.

Lemon Vervain Powder by TerraVita Premium Collection: Common Questions

Does Lemon Vervain Powder by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Lemon Vervain Powder has a known interaction with 1 medication. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Lemon Vervain Powder contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Will lemon vervain upset my stomach?
It can. In one trial, people drinking fresh lemon juice at medicinal doses reported heartburn in about 1 in 5 cases and stomach pain in a smaller number. Regular food amounts of lemon are fine, but this powder is a concentrated form. If you have reflux or a sensitive stomach, start small and see how you tolerate it.
Does lemon vervain actually work for hay fever or anxiety?
The evidence we have isn't strong enough to say. For hay fever, anxiety, respiratory infections, high blood pressure, and kidney stones, the data is insufficient to rate whether lemon vervain helps. If you're hoping to treat one of these, talk with your doctor about options with better evidence.
Is it safe to use while breastfeeding?
The safety data on medicinal amounts of lemon vervain during breastfeeding isn't on file. Lemon as a food is fine, but because this is a powder supplement, talk with your doctor or pharmacist about whether it's right for you during breastfeeding.
Can I take this if I'm on itraconazole for a fungal infection?
Not without checking first. Lemon vervain may increase how much itraconazole your body absorbs and strengthen its effects. Mention this product to your doctor or pharmacist before starting it if you're on that medication.
What is lemon vervain used for?
Traditionally, it's been used for digestive and respiratory support. This product doesn't have reliable evidence backing those uses yet, but people have been drinking lemon vervain tea for those purposes for a long time.
